Now that I think about it, how many active Shibukai are there? I mean world government's lost alot of them throughout the course of the White Beard War either via death or defection.

Jinbei has probably going to have his title stripped. Hancock's status is questionable since she did attack marines during the conflict and aid Luffy. Moria I guess is officially dead. And black beard defected and pretty much bitch slapped the world government while simultaneously humiliating them.

So that leaves Don Flamingo, Mihawk, and Kuma, so there's 4 positions that need to be filled post white beard war.
